UltiMaker unveils a new Secure Line of 3D printing products built for defense and high-security environments. Leading the launch are the UltiMaker S6 Secure and UltiMaker S8 Secure, two solutions built to provide on-demand production capabilities across land, sea, and air operations.
Built on UltiMaker’s platform, the S6 Secure and S8 Secure combine industrial performance with security features designed to meet defense IT standards.
“The Secure Line represents a strategic leap in making additive manufacturing a trusted and deployable asset for defense organizations,” says Andy Middleton, senior vice president EMEA and Global Marketing at UltiMaker. “By combining industrial-grade 3D printing with uncompromising security, the Secure Line enables the production of mission-critical components at the point of need, safely, reliably, and with full control over their data and infrastructure.”
Designed for operations in variable conditions, Secure Line printers offer air-gapped, USB-only workflows, with no Wi-Fi, no external cameras, and no unverified third-party devices, eliminating common vectors for espionage, data theft, or remote intrusion, Ultimaker explains.
Key security features include factory-flashed, tamper-resistant firmware; encrypted and auditable file handling; hardware-sealed components for field integrity; and no cloud dependencies or external attack surfaces.
These features ensure operational control and auditability, enabling defense forces to manufacture components while maintaining high levels of data control, protection, and system security.
The S6 Secure and S8 Secure are engineered to bring industrial additive manufacturing capabilities from the lab to the field. With compact form factors and rugged construction, they enable operation in mobile units, military bases, and naval deployments; on-demand production of parts and tools; and minimized downtime and reduced dependency on supply chains.
“With Secure Line, we give defense organizations something they have not had before: industrial 3D printers they can fully trust anywhere in the world,” says Arjen Dirks, chief technology officer at UltiMaker. “We designed our Secure Line products with security built into every layer and to meet internationally recognized standards, combining reproducibility and long-term reliability in a form that guarantees tactical capability in defense environments.”
Powered by the UltiMaker Cheetah motion planner, high-flow print cores, and an improved feeder system, S6 Secure and S8 Secure deliver productivity with improved print quality. Combined with a wide range of engineering-grade materials in the UltiMaker Marketplace and multi-material printing capabilities, the Secure Line offers material flexibility in a secure environment, according to Ultimaker.
The Secure Line is manufactured in UltiMaker’s manufacturing facility in Zaltbommel, Netherlands, adhering to European standards for quality, data security, and compliance. UltiMaker 3D printing ecosystem has been used by NATO-aligned organizations globally to power parts production. Each Secure Line product is produced in limited batches and tailored to requirements of Defense industry users. Availability of the Secure Line for qualified defense and aerospace organizations is expected to begin now.
